Requested by Meg_Weasley24: Y/N is watching her nephew at her and Tom's house and Tom is being really cute with the baby. When the parent picks him up, Tom tells Y/N that they should have a baby.

Tom's P.O.V

Tom sat in the home office, his fingers typing away at his laptop as he worked.

"Tommy." He looked up and gave his beautiful girlfriend, Y/N, a small smile as she stood at the doorway.

"What's up, darling?" He asked.

"Kiera and John need a babysitter for Oliver this weekend. We okay to take him Saturday night?" She smiled sheepishly. His eyes widened slightly. Him and Y/N had been together for five years now, living together for three. And recently, he'd started to think about their future together. More accurately, the idea of them starting a family. And so he felt like the opportunity to babysit Y/N's month-old nephew was the perfect chance to show Y/N that he'd make a great dad, and then to bring it up to her afterwards. This was going to be perfect.

"Yeah, course, Olly is super cute, I'm down to take him." He chuckled.

"Brill, thanks, Tommy." She smiled, making him return it as she left the doorway. His eyes wandered, his heart jumping at the idea of finally talking to Y/N about them having a baby. He was nervous, for sure, but it was an idea that he very much liked.

Y/N's P.O.V

"Kiera, hey!" I squealed and hugged my sister, making her laugh and return the hug as we stood at mine and Tom's open front door.

"How have you been?" She asked.

"We've been good. What about you, you had a baby a month ago." I chuckled, making her smile as John pushed the buggy with Oliver in it into the house.

"We're so good. Thank you guys so much for agreeing to watch him." She smiled, making Tom and I return it as we looked into the pram.

"Aw, he's gotten so big. Hey, sunshine." Tom smiled at Oliver, making him coo and look up at Tom as my boyfriend gently tickled his stomach.

"Yeah, he's grown so much. You sure that you can handle it?" Kiera teased.

"We'll be fine. Go, you two, have a nice night out." I nodded as I gently started to usher them out of the door.

"Thank you guys so much, have fun with him!" Kiera called as they got back into the car.

"Bye." I smiled, my hand shutting the door before turning to face Tom and Oliver.

"Are you ready to do this?" I asked.

"More than." He smiled, making me return it as he pushed the buggy into the living room.

Tom and I sat in the living room, my legs over his lap as Oliver lay in his buggy. He started to whimper and cry, making us look at the buggy.

"Here we go." I sighed as I started to move my legs.

"No, it's okay, I've got him." Tom shrugged, making me look at him as he gently lifted my legs from his lap and stood up from the sofa.

"You sure? He could need changing." I chuckled.

"Yeah it's fine, could use practice anyway for when we have a kid." He mumbled. My eyes widened at his words, my breath hitching slightly at the comment. When we had a kid. I knew that Tom and I were starting to discuss our future together, but I didn't know that we were that close to a conversation about a baby. Not that I minded, though. Tom didn't at all seem phased by his own words as he leant down and gently put his hands around Oliver to pick him up.

"Here we go, hey, bud." He chuckled, making me smile and bite my lip as I saw my boyfriend with my baby nephew. And maybe if things played out for us, he'd be holding our own baby in a year or two.

"I can't smell anything, so I think that he's good. I think that he's just wanting a cuddle, hey?" Tom smiled over-enthusiastically at Oliver as he took him into his arms before sitting down with him. Oliver looked at Tom, the little boy in awe of his uncle as he reached his hand out to touch Tom's face. Tom gasped playfully and opened his mouth, Oliver squealing and laughing as he stuck the tips of his fingers into Tom's mouth. Tom pretended to bite Oliver's fingers, making the baby squeal and laugh as they continued to play.

I walked back into the living room, my heart immediately filling with love as I saw it. Tom was sat cross-legged on the carpet, his lips carved into a smile as Oliver lay on the floor in front of him and Tom gently moved his legs around with his hands. Oliver had been at our house for a few hours now, and Tom hadn't put him back in his buggy since he'd first taken him out. Tom had fed him, changed him, played with him. Everything that needed to be done for Oliver, Tom had done it without even being asked. It was almost as if he was trying to prove something to me.

"Are you having fun with Uncle Tom? Yes you are, aren't you?" He cooed and shook his head. I bit my lip, tears pricking my eyes as I sat down next to him and rested my head on his shoulder.

"You're really good with him, you know. He seems to really like you." I chuckled and bit my lip. He looked at me.

"Yeah? Good because I like him too. He's a cool little guy, it's been amazing to look after him." He smiled, making me return it as he continued to move Oliver's legs about.

"Was he okay?" Kiera asked, Oliver being gently bobbed up and down in Tom's arms as we stood at the open front door.

"He's been a pleasure to watch, no bother at all." Tom smiled at Oliver, making the little boy squeal playfully.

"I'm glad. We might use you for childcare again, then." Kiera teased.

"We would say yes in an instant." I reassured.

"We better be heading off." John nodded, making Kiera return it. Tom looked at Oliver.

"Alright, sunshine, time to go home." Tom smiled at him, the boy squealing as Tom gently lay him down in his buggy. I bit my lip, my heart filled with so much love for my boyfriend as Kiera and I watched the interaction.

"Hey." Kiera spoke quietly as she nudged my arm, making me look at her. She bit her lip and looked at Tom.

"If you guys ever decide to have a baby, he's going to make an amazing dad." she reassured. I smiled and bit my lip, tears pricking my eyes at the thought of starting our own family.

"I know." I nodded. She gave me a small smile, her hand reassuringly squeezing my arm as she took Oliver's buggy and started to push it out of the house.

"Again, thanks so much for watching him." John smiled as I leant against the doorway and Tom curled his arm around my waist.

"Completely our pleasure. Drive safe, guys." Tom returned, both of us waving before shutting the door.

"Well, that was fun, wasn't it?" I chuckled as I turned to face Tom. He nodded and looked down, his Adam's apple bobbing in a gulp as he shoved his hands into his jean pockets.

"Y-yeah, it really was, um...I actually want to talk to you about something, love." he nodded as he looked back up at me. My eyebrows furrowed.

"Sure, Tommy, what's up?" I asked. He bit his lip, though I could tell that he was really nervous from his panicked eyes as he curled his arms around my waist and I rested my hands on his chest.

"I just...originally, I said yes to taking Oliver because I've been thinking a lot about our future, including potentially having kids. And so, I figured that he was a good way to test the waters." he admitted. My eyes widened slightly, my heart almost stopping. I hadn't realised that this entire time, Tom had also been thinking about us having a baby.

"And, well, looking after him just solidified what I thought that I wanted. He was so fucking cute, and so fun and playful, and I want us to have that. I want to have a baby, with you." he confessed. I bit my lip, tears pricking my eyes as I raised my hands to cup his face. I pulled him down and smashed our lips together, him immediately returning it as he curled his arms further around my body. I broke the kiss and joined our foreheads as I looked at him.

"I've been thinking about the exact same thing recently. So, yes, Tom, I'd love to start a family with you. I'd love to have a baby with you." I smiled and shook his head. A breathless laugh left his lips, a tear running down both of our faces as he also cupped my face with his hands.

"We're really doing this. We're really going to start trying for a baby!" he laughed.

"Yes, we are. And I can't wait." I shook my head. He returned it and gave me one of the biggest smiles that I'd ever seen from him, making me laugh as he leant down and smashed our lips together again.
